Title: Method for etching metal sheet
Inventor: UEDA RYUJI
IPC: G02B5/20
Filed: 1990-07-04
Abstract: PURPOSE:To make grooves for printing elements uniform in depth while nearly preventing the increase of the width by spraying a ferric chloride etching soln. having a high concn. at a high temp. on the surface of a metal sheet with a patternwise formed resist under a high pressure at a narrow interval. CONSTITUTION:A ferric chloride soln. having >47 deg.Be' conc. at >60 deg.C is sprayed on the surface of a metal sheet with a patternwise formed resist under >2 kg f/cm<2> pressure at <15 cm interval. By this method, etching proceeds more remarkably in the thickness direction of the sheet than in the transverse direction and grooves for printing elements are not considerably extended in the transverse direction but are deepened, accordingly grooves for printing elements are accurately made while nearly preventing shallowing at both sides.

Title: Aggregate and damping concrete
Inventor: ISHIKAWA NOBORU
IPC: E04B1/98
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To inexpensively realize the damping performance in no need of a sophisticated structure by using hollow vessels containing particle bodies which are enclosed in the vessels so that the particles may be freely movable in the vessels as an aggregate to be admixed to a hardening material such as concrete. SOLUTION: The specific gravity of this aggregate is set to an almost same value as that of the hardening material and the aggregate is admixed to the hardening material to form a variety of structures. Even when these structures are exposed to vibrations due to earth-quakes, winds, traffics and the like, the particles in the vessels move to damp the vibration. An example of damping concrete according to this invention is given in the figure. The damping aggregate 2 is, for example, a flat sphere and is constituted with a hollow vessel 3 as an outer shell and a plurality of particle bodies 4 (for example, a metal with particle sizes of 1-0.1mm) enclosed in the vessel 3.  The vessel 3 is made of metal, ceramic, hardened cement body, plastic resin and particularly a material having a high strength than that of the concrete main body is used in order to secure the high strength than that of the concrete main body.

Title: Automatic measuring instrument for vitrinite reflectivity
Inventor: KURITA YUJI
IPC: G01N21/17
Filed: 1989-07-11
Abstract: PURPOSE:To automatically measure vitrinite reflectivity by connecting an image input section to an image processing section and executing a required program. CONSTITUTION:A standard sample is imposed on an object stage 1 and an instruction is inputted from a mouse device 1 to a processor 16 for control to start the program for automatic formation of a calibration curve, and to calculate the calibration curve equation to convert the luminance on the image projected on a monitor TV 14 to the reflectivity. The reflectivity is stored in a memory medium. A sample 2 to be measured is then imposed on the stage 1 and an instruction is inputted from the mouse device 1 to the processor 16 to start the program for controlling the program execution sequence to read the calibration curve equation. The image input program is then started to store the image of the sample 2 in an image memory 11. Only the part corresponding to the vitrinite in the image of the memory 11 is automatically extracted and is shaped. The luminance of each piece of the shaped particle images is automatically measured and is substd. in the calibration curve equation, by which the luminance is converted to the reflectivity data. The data is recorded. The automatic measurement of the vitrinite reflectivity is completed by repeating such processing.

Title: False random signal generation circuit
Inventor: SASAKI YOSHIHITO
IPC: H03K3/84
Filed: 1992-07-06
Abstract: PURPOSE:To obtain a stable false random signal even when phase difference occurs between a clock signal and an enable signal by attaching a data selector on each D-FF which comprises a shift register. CONSTITUTION:The data selectors 31-35 select a word 1 terminal when a word select signal shows L and a word 2 terminal when it shows H, and outputs the signal of a selected terminal. Since the data selector selects the word 2 terminal when the enable signal shows H and the word select signal shows H, the same operation as that of an ordinary false random generation circuit can be performed. Meanwhile, when the enable signal shows L and the word select signal shows L, a feedback path from output to input is formed at each D-FF via the word 1 terminal, and each D-FF holds a logic level just before the enable signal goes to L. Thereby, the clock signal is supplied to the D-FF independently of the phase difference between the enable signal, thereby, a false random signal generated by the correct number of clocks can be obtained.

Title: Method and device for identifying similar color area of spot color image
Inventor: JIEIMUZU JIEE GURAHAMU
IPC: G06V10/56
Filed: 1992-06-11
Abstract: PURPOSE: To replace the similar color area of a spot color image with a dominant color by identifying the similar color area. CONSTITUTION: A spot color image is generated by scanning an original image and the colors in the image are classified. Dominant colors are decided from the frequencies of occurrence of the classified colors. The original image is again scanned and the spot color image is again generated, and then, the colors in the image are replaced with the closest one of the dominant colors. Therefore, the storing and operating efficiencies are improved, because the kinds of colors are reduced.
